internal static class in assembly reflection

Suppose we have a class like :

public void Login(string serverName, string username, string password)
{
    Server.ServerName = serverName;
    Server.DatabaseName = db;
    Server.Username = username;
    Server.Password = password;
    this.Initiate();
} 
private void Initiate()
{
    Server.IsAuthorized = true;
} 
public Patient GetPatient(string admCode)
{
    if (Server.IsAuthorized)
    { 
    } 
}

and internal static class is something like:

internal static class Server
{ 
  internal static string ServerName { get; set; } 
  internal static string DatabaseName { get; set; } 
  internal static bool IsAuthorized { get; set; } 
  public static string Username { get; set; } 
  public static string Password { get; set; }  
}

When I want to execute methods by reflection the return value is empty for GetPatient like:

Assembly assembly = Assembly.LoadFrom(path);
Type myType = assembly.GetType("myType");  
MethodInfo loginMethod = myType.GetMethod("Login");
MethodInfo getPatient = myType.GetMethod("GetPatient"); 
object obj = Activator.CreateInstance(myType);  
var login = loginMethod.Invoke(obj, new object[] { m_ServerAddress, _userName, _pass });  
var objPatient = getPatient.Invoke(obj, new object[] { id });

Is this because of that internal static class?

Thanks in advance.
